A Different Me focuses less on heartache and more on maturity of her vocals and lyrics. Cole explained that, "The first two albums were more…painful. It's a different me this time: a young woman who's still growing and finding myself, exploring life through different routes musically and in other areas. I wrote more about other people's situations than my own. I'm moving forward."
On the songwriting process, Cole stated, "When I hear something, I hear it—it doesn't take me three, four, five times to hear a song and say, 'OK, let's write.' If I don't write to it right off the bat, it's not working." All the songs on the album were written or co-written by Cole. Guest appearances include Amina, Nas, Monica and 2Pac. Along with the album, Cole was developing a movie based on her life. A screenwriter has develop the script with Cole in 2009.
The album was released on December 16, 2008. Earlier that week, Cole made an appearance on BET's 106 and Park being interviewed and introducing the video to "Playa Cardz Right". Cole also embarked on the I Am Music Tour in late 2008 and A Different Me Tour in the summer of 2009. She was featured in magazines Billboard, WordUp and VIBE from winter of 2008 to spring of 2009.
The album received generally favorable reviews. Andy Kellman of Allmusic gave the album four out of five stars, calling the album "Cole's most free-spirited and adventurous album to date", going on to say that there are "at least seven songs here that rate as highly as the best from the first two albums". Jim Farber of Daily News also gave the album four out of five stars, noting that "Cole's assertions of sweetness and light hardly prove as seamless, or simple, as her songs declare". He declares that "her makeover feels less like a day at the spa than a night at the shrink", going on to say that "instead of seeming harrowing or dark", the album's result is "soulful and fulfilling".The Boston Globe said that "Cole emphatically dares to be different—and pretty great". On the contrary, Jon Caramanica of The New York Times noted that Cole "let go of her doubt", going on to say that "it's missed".
